I/O Signal
explanation
EXP 1 IN
External power input for photocouplers of MON, STA, +EL, -EL, ORG
and SD. The anode side of the photocouplers for the above signals is
pulled up to EXP with 1K
Ω
. EXP input range : DC4.5V to 7V
MON 2 IN
Excitation ON/OFF Input
Photocoupler ON : Excitation ON
Photocoupler OFF : Excitation OFF
When photocoupler is OFF, excitation ON/OFF can be controlled by
internal SW1-2.
Note 1.
STA 3 IN
Operation starts / Operation stops
Photocoupler ON : Operation starts.
Photocoupler OFF : Operation stops.
When photocoupler is OFF, excitation ON/OFF can be controlled by
internal SW1-1.
Note 1
+EL 4 IN
+ End limit
Photocoupler ON : Limit ON
Photocoupler OFF : Limit OFF
Note 2
-EL 5 IN
- End limit
Photocoupler ON : Limit ON
Photocoupler OFF : Limit OFF
Note 2
ORG 6 IN
Origin position signal
Photocoupler ON : Origin position ON
Photocoupler OFF : Origin position OFF
Note 3
SD 7 IN
Deceleration signal
Photocoupler ON : Deceleration ON
Photocoupler OFF : Deceleration OFF
Note 3
END 8 OUT
Open collector output (SN74LV07)
Outputs LOW when operation is completed
PLS 9
OUT
Open collector output (SN74LV07)
Outputs pulse strings specified by the RENV1 of PCD2112
Note 4
DIR 10
OUT
Open collector output (SN74LV07)
Outputs pulse strings specified by the RENV1 of PCD2112
Note 4
MOT 11 OUT
Open collector output (SN74LV07)
Outputs LOW when excitation is ON
+5V 12
OUT
GND 13 IN
O5V power supply of the board
Note 5
Note 1.
: When signals are input from outside, make SW1-1 and SW1-2 OFF.
Note 2.
: The logic of end limit is selected by SW1-5. The above table shows a condition with SW1-5 being OFF.
Note 3. :
The logic of ORG and SD is selected by software. The above table shows the default.
Note 4. :
You can select between use of the integrated driver or pulse string output by using SW1-3.
When output pulse string is selected, you can change the pulse output method such as CW/CCW or
PLS/DIR by changing the RMD in the RENV1 of PCD2112.
Note 5. :
You can use it when +5V power supply for EXP cannot be prepared at the test. You can use them by
conn5V terminals (CN3-13) to EXP(CN3-1) and turning input signals ON/OFF to GND
(CN3-13). (Do not use +5V power for any signals other than input and output signals.)
